Moon is a side-scrolling game where the player must drive a moon buggy from one station on the Moon to another, all while avoiding crashing or getting destroyed by alien ships. The vehicle is constantly moving right and the player can speed up or slow down, jump, and shoot (simultaneously firing upwards and forwards.) There are 25 checkpoints along the way, each symbolized with a letter from A to Z and serving as a respawn point. Every five checkpoints mark a separate "stage" within the entire course; reaching the end of a stage under the par time grants a large score bonus.
The player must navigate through obstacles such as rocks, pits, and UFOs which fire at the player or bombard the ground (creating pits). Later, stationary tanks and landmines are introduced, along with carnivorous plants that pop up out of pits. Rocket cars also stalk the buggy from behind before rushing forward in an attempt to ram it down.
After completing the first course, the player can attempt the harder Champion Course.
Moon was released on the Nintendo Switch in 2019 for players aged 18 and above.
